VSIX - How to include XML documentation files in package?

I've found the following article that nicely describes how PDB files of project references can be included in the VSIX package: http://www.cazzulino.com/include-pdbs-in-vsix.html.

Now I would like to do the same, but for documentation XML files that are generated by project references. I see that the XML files are already copied to the output directory of the VSIX project, but how can I make sure that they are added to the .VSIX file as well?

Solution

Answering my own question:

Apparently there is also a "DocumentationProjectOutputGroup" output group. This output group can then be added to all project references in the following way:

<PropertyGroup>
    <DefaultIncludeOutputGroupsInVSIX>
        BuiltProjectOutputGroup;
        DebugSymbolsProjectOutputGroup;
        GetCopyToOutputDirectoryItems;
        SatelliteDllsProjectOutputGroup;
        BuiltProjectOutputGroupDependencies;
        DocumentationProjectOutputGroup;
        SatelliteDllsProjectOutputGroupDependencies
    </DefaultIncludeOutputGroupsInVSIX>
</PropertyGroup>

<ItemDefinitionGroup>
    <ProjectReference>
        <IncludeOutputGroupsInVSIX>$(DefaultIncludeOutputGroupsInVSIX)</IncludeOutputGroupsInVSIX>
    </ProjectReference>
</ItemDefinitionGroup>
